About Walnut Creek Watershed

The Walnut Creek Watershed stretches 83 square-miles across Polk and Dallas counties, divided nearly evenly across rural and urban areas. Following a decade where more than six square miles of watershed developed into urban land uses, Walnut Creek continues to be one of the fastest urbanizing areas in Iowa.As the watershed has changed so have the environmental conditions.


Flooding, nutrient loading, bacteria and eroded soils impact public health, reduce habitat and undermine the ability of Walnut Creek to serve as a Central Iowa amenity. Walnut Creek flows into the Racoon River less than a mile from the Des Moines Water Works’ intake for a public water supply serving nearly one-half million users. Walnut Creek is a priority area to focus restoration efforts. The Walnut Creek Watershed Management Authority is working to collaboratively address watershed issues.
